One of the major problems recognized today with barrel plasma etcher reactors is the run to run reproducibility during the resist-hardening process. The process may be significantly improved by: 1) Aluminum Faraday cage DC bias voltage and 2) Monitoring and controlling the UV emission spectroscopy.
